I am guessing that the original internal battery is similar to the one I have in my solar powered watch. They can last 20 or more years and survive with very little charge for an extended time.

I have had mine for over 15 years and the "solar panel" is a 2mm or so ring around the watch face.

Mine is called CTL1616.

Thanks for the possible explanation.
I wish that whatever Minolta did with internal batteries, Nikon had done with their pathetic Coolpix internal batteries.

There are three typical options used for settings retention. First is using a simple battery. These are usually some kind of lithium technology button cell which are not chargeable in the device.  This can provide settings retention for a couple of years of no main battery. The second approach is to have the retention battery chargeable. This is a better option as the life can be many years but still does have a limit on charge cycles. The third method is using a device called a super capacitor. This has a very long life but less hold over time than a chargeable battery.
